Application October 15, 1934, Serial No. 748,418

4 Claims.

The object of my present invention is to produce an insecticide and deodorizing volatile pad, in the construction of which eflicient provision is made for promoting substantial uniformity in the rate of volatilization of the insecticide or deodorant, both in the integral or undiminished article as well as in the separate portions-thereof into which the article as a whole is designe and adapted to be frangibly divisible. I

My invention relates to articles comprising each a supporting body or assembling member which may be made of pasteboard or any similar frangible substance suitable for the intended purpose.

In the completed pad, the said assembling member is coated as by moulding it, or dipping it repeatedly, by preference, in a volume of any suitable volatilizable deodorant material in a fluid state, such, for example, as naphthalene. Said substance is, at the time of such coating operation, in a liquid or semi-liquid state, but becomeshardened upon exposure for a brief interval of time to the atmosphere at ordinary temperatures. v

This hardening of the coating is of a fugitive nature and yields gradually to the further action of the atmosphere to efiect gradual volatilization of the coating material to such degree as will, in time, slowly eliminate the coating entirely from the assembling member to which it adheresafter the initial hardening operation of the coating takes place.

Now it has been found desirable to make provision for segregating my pad as a whole into conveniently divisible portions, in order to render the article available for fumigant purpose and under conditions which militate against the access from a single remote source of the fumes of the fumlgant into the body of material to be treated. Besides, the coating of the comparatively small divisible portions volatilizes in much. shorter time than the coating of the pad as a serve to explicate the principle of the invention in any modification of the form of its embodiment which may be preferred.

In the drawing, Figure I is a. side elevation of my invention complete in present preferred form of embodi ment.

Figure II is a similar view of the, body part or assembling member without the disinfectant coating shown in Figure I.

Figure III is a, transverse view taken on the line III--III of Figure I.

Figure IV is a similar view on the line IV-IV of Figure I.

Figure V is a similar view on the line VV of Fi e I.

Figure VI is a longitudinal sectional view on the line VI-VI of Figure I.

Figure VII is a similar view on the line VII- of- Figure I.

Of the reference numbers on the drawing, I indicates what has already been referred to as the assembling body of my device. It may be provided with a perforation 2 by which the article may be suspended to advantage in use.

The pad as a whole is provided witlrweakening lines along which its segregation into divisible portions is facilitated. may be made available by practical elimination of the coating material of the pad so the segregation of the pad demands only the severing of the fragile member I as desired. The preferred mode of defining such lines is by the fissure 3 formed in the member I, which defines an elongated fingerlike member 4 from the main body of the member. The presence of the fissure 3, as locating a weakening line in the pad Such weakening lines as a whole is preferred because it not only provides for a complete severance of the member 4 from the body part,- wheneversuch severance is desired, but the member 4 becomes in the coating operation, encased on all sides by a disaperture 9, a transverse weakening line l0, anda longitudinal weakening line I I, shown in Figure 11, may be provided.

It being borne in mind that in the coating process a superficial layer of fumigant material is caused to be built up on the member by its adherence mediately or immediately thereto..

It will appear that the entire lower portion of the body part will be provided with such a layer, corresponding, substantially, to the coating 5 above referred to, and that small sections of the pad may be at will broken away by hand from the remainder of the pad without disturbing the remainder of the article.

Such segregated portions are used to provide a distribution of the fumigant at intervals in the body of the material undergoing treatment in such locations as maybe diificult of impregnation by fumes of fumigant desired from a more remote source, such for instance as a pad suspended within an enclosed chamber which is entirely efiicacious under favorable conditions.

The presence of circumscribed apertures in the assembling member such, for example, as the apertures 6, 1, 8, 9 and I0, as illustrated, aifords means for securing the coating and the assembling member into close mechanical connection by a rivet-like eiifect in each instance where such connection is employed, thereby tending to prevent any disposition to cleavage between the coating and the member I. It will therefore be obvious that the number of circumscribed apertures may be multiplied as occasion may recommend to be advantageous in practice.

What I claim is:

' 1. A fumigant pad consisting of an assembling member having fissures in it defining finger-like 'members, in combination with a coating of volatilizable material, the coating. being distributed in substantially uniform thickness over each finger-defined member, the coating of each finger-like member being separated in the line of the fissure which defines it.

2. In a new article of manufacture, a volatile insecticide pad consisting of a support having spaced portions, and a volatilizable substance adhering to the portions and having a frangible connection in the spaces therebetween.

3. In a new article of manufacture, a volatile insecticide pad consisting of a support having sections cut out to provide portions defined by intervening spaces, and a volatilizable substance adhering to such portions and having a frangible connection between and within the spaces defining such portions.

4. A fumigant pad consisting of an assembling member having fissures in it defining finger-like members, in combination with a coating of volatilizable material, the coating of each fingerlike member being separated in the line of the fissure which defines it.
